Audio doesn't work without an external input
Recently I've been experiencing a problem where unless my headphones/earbuds are plugged into my macbook no sound works (on the speaker icon it is just grey) and a red light comes out of the external speaker port. I'm pretty sure it's not the internal speakers as when restart my computer the apple start up sound works. Any suggestions would be much apprectiated. Thanks

Timed sequence doesn't work right with external timing source
I'll describe first what I want to accomplish and
then maybe someone can read further and suggest why the attached VI
doesn't work. I have a SMU (PXI 4130) that takes differing amounts of
time to set a current depending on if the setting spans a range
boundary. I want to be able to make that SMU setting and then wait a
specific amount of time (sometimes 1 msec). If the SMU takes a little
longer to return then I want that extra time to come out of the wait
time. To do this I figured I would need an external time source to
control a timed sequence to give better than the normal 1 msec
resolution. So now onto the problems I'm having.
I've
got two problems here that I would really appreciate some insight on.
The attached VI is the subject of both problems (as is the VI is
worthless, but it illustrates the problem). Note that you need some
type of DAQ board with a counter on it to run it.
I can't
figure out why this timed sequence doesn't work with an external timing
source. It works mostly as expected (see next problem) with the
internal source, but fails miserably with the external source. Run the
VI as is to get a baseline. Then connect the DAQmx Create Timing Source
VI to the Source Name input of the timed structure. It seems like it
should run exactly the same both ways.
Problem 2 (run with the
internal timing source). The VI should take the same amount of time to
execute regardless of the input to the Wait VI (within reason of
course). That's actually the main impetus for this whole exercise. But
according to the Actual End indicator it runs faster with a longer wait
time.

test timed sequence.vi 144 KBHi George, I have been playing with the code that you have posted and I think I am seeing what your concern is with regards to the first problem that you stated. Without running the code I would expect both internal and external timing to cause the VI to run in the exact same manner, however obviously that is not the case. I am currently looking into this behavior and I will post you a response as soon as I have an answer for you.
As for the second problem, If you look at the manner in which you have coded this VI, a 1ms wait in the first frame will lead to a calculation of 1999ms wait in the second frame, and thus 5 iterations of 1999ms or about 99,995ms total running time. If you increase the wait in the first frame to say 50ms, then an overall all wait of 1950ms is calculated in the second frame so not the overall iteration time is now 1950 which, over 5 iteration leads to 99,750ms thus as you increase the wait in the first loop the overall loop duration will be less. This is expected behavior.
Again I will post back once I have a clarification on the internal vs external timing.

I think that you have multiple sound devices and their boot order changes after each reboot.

Audio doesn't work after encoding
I have finished editing a video and gone to export it as a WMV and the audio doesn't work; there is just a buzzing noise.
The audio works fine on the timeline, but i just cannot export it.
Any ideas what's gone wrong?Hi ATR, thanks for getting back to me. Here is all the info you required:
It's Premiere Elements 10 on a Windows 7 PC.
The source media is a mix of WMV, MP3 audio and JPGs.
The project settings are:
Editing Mode: DSLR
Timebase: 25.00 frames/second
Frame size: 1920 x 1080
Pixel Aspect Ratio: Square Pixels (1.0)
The export settings are:
Windows Media:
Presets: HD 720p 25
File type: Windows media
Frame size: 1280 x 720
Fps: 25
Audio settings: 440 kbps, 96kHz, 2 channel 24 bit VBR (I have tried it with a number of different variations on this and still had no luck)
I’ve tried opening with Windows media player as well as VLC. Neither are having it. -

Hello,
I have a problem with my iPhone 3G. Audio (speaker, headphones, microphone) stops working without reason till I reset to default. It happens every day. When I plug in headphones it doesn't recognize they're plugged in. When I try to use skype it says no audio hardware available.
I tried:
- plug and unplug headphones several times
- restore with and without using backup
- iOS 4.1 and 4.2.1
- reset to default settings (which works but I can't do it on daily basis)
- restart multiple times
Thanks for suggestions!I found the answer here: http://discussions.apple.com/thread.jspa?threadID=2037740&start=0&tstart=0

Help my audio doesn't work on my MacBook Pro
Ok so this is whatt happend: I was just on my Mac with my headphones, than decided to stop, so I pulled my headphones out. The next day I want to watch some videos but my audio didn't work, I went system prefrence and to "sound" to "input" and my mute was off, the sound was up, and the "Internal-Speakers" was slected.
1. Remove the headphone.
If you see red light in the headphone port, plug the headphone
in and out of the port 5 or 6 times to flip the microswitch inside.
Sound output may be stuck in the digital mode.
2. Reset PRAM. http://support.apple.com/kb/PH4405
3. Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".

Click the Built-in Output.
Under Mute any of the boxes checked? If so, uncheck it. -
Html5 audio doesn't work for mp3s.
I can't seem to get tag <audio> working with mp3s on my system(FF 24, Win 7 x64). I tried some wav files, those work ok. But whenever i try to play mp3 file, the html5 player just flashes for a few milliseconds and then disappears. So, is there a bitrate limitation (or any other limitation) for html5 audio tag on mp3s?
Here's an example of code and one of the mp3 files I am trying to use - http://dindo.wz.cz/jukebox.html .
(file http://dindo.wz.cz/Galaxy32Star4.mp3 )
The console (ctrl+shift+k) gives these errors (rough translation):
[14:07:48.861] Type HTTP "Content-Type" "audio/mpeg" is not supported. Loading of media http://dindo.wz.cz/Galaxy32Star4.mp3 has failed. @ http://dindo.wz.cz/jukebox.html
[14:07:48.862] Couldn't load any of candidate sources. Loading of media was suspended. @ http://dindo.wz.cz/jukebox.html
p.s: Even the w3c example doesn't work when i remove the ogg source. (http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_audio_all).can you replicate the issue, when you create a new profile for testing purposes?: [[Use the Profile Manager to create and remove Firefox profiles]]

X-fi Xtreme Audio doesn't work in Windows 7 64 bit
Hello everyone,
I know this is a known issue and I've found many topics on this, but still I can't find any solution and I hope you can help.
I've a Creative X-fi Xtreme Audio that was working perfectly under Windows XP SP3 but then I've upgraded to Windows 7 64 bit and the sound coming out from my speakers is awful. I've installed the latest driver from creative home site, I've updated the OS via "microsoft Update", I've tried many suggestions I've found on the web to solve this, like phisically change the PCI slot of the sound card, or reduce the ram ammount via msconfig but it didn't work. I've tried some custom driver either, the support pack 2.7 by Daniel?K. but nothing... I'm still at the starting point.
What should I do?
This is my actual configuration:
OS: Microsoft Windows 7 Premium SP v 6..760
CPU: AMD Athlon 64x2 6000+
MB: Asus M3N78 SE (with the latest bios version 002)
Ram: 4gb
Video: nVidia GeForce GT 220I use CS4 on a Windows 7 64-bit computer.
I noticed that none of the extensions I installed with the Extension Manager don't appear at all in any of the CS4 programs.
Can anyone tell me why this doesn't work or how to solve this problem?

Edge audio doesn't work in DPS project
Being very happy after latest update of Edge CC, I've decided to make DPS project for iPad.
First, when I chose "autoplay" button for audio timeline, I got a warning about sound autoplay option is not supported at digital devices (??). So what should I do? To not use the autoplay?
Second, a preview of Edge animation in web-browser works perfect (both background sound and a sound for user interaction) - BUT when I put .oam file in DPS, the sound just DOESN'T WORK.
I tried everything - check-uncheck "autoplay", check-uncheck "preload audio", put an audio as a trigger.. no sound in iPad.
And when I put audio file directly into Indesign, a sound works perfect in iPad.
What's going on?Agapyla wrote:
so the idea is all projects for iOS cannot use Edge Audio feature that was just released last month? At least in full way, as it is shown in built-in Edge Tutorial (autoplay)?
No, not exactly. iOS and other mobile devices can playback HTML 5 audio, which is what Animate outputs.
But the fact of the matter is that autoplay for audio (and preloading) is not supported by mobile devices - it's a limitation manufacturers build into their devices. Therefore, to use audio from Animate in mobile devices, you have to initiate audio playback from a user event, such as touchstart or click.
We warn you of this in Edge Animate when you turn on autoplay (warnings appear at the bottom of the Stage). -
